Atomic-scale mechanism of enhanced electron-phonon coupling at the interface of MgB thin film
Xiaowen Zhang, Tiequan Xu, Ruochen Shi +7
In this study, we explore the heterointerface of MgB film on SiC substrate at atomic scale using electron microscopy and spectroscopy. We detect ~1 nm MgO between MgB and S…

Atomic-scale observation of localized phonons at FeSe/SrTiO3 interface
Ruochen Sh, Qize Li, Xiaofeng Xu +11
In single unit-cell FeSe grown on SrTiO3, the superconductivity transition temperature features a significant enhancement. Local phonon modes at the interface associated with elect…
